I’ve actually just had a look at Dandelife and was initially confused by words like “Life” “Streams” and “World” which meant nothing to me. I’m sure it’s a good service but, like I said, I have no reason to switch. Yet. Thanks for bringing it to my attention though.

You asked me to tell you “what FriendFeed does that other aggregators aren’t already doing with a much nicer interface and other, less intrusive means of sharing.” I can’t answer that but I’ll remind you that (i) you don’t need to be the first to do something to be the best and (ii) one person’s heaven is another person’s hell.

Using FriendFeed as an example; this is the main reason why I’m so hopeful about a true Semantic Web. Friend Feed just dumps at me, with no friendly way in place to sort through the information. The same is true of Spokeo. Take, for instance, the day that I switched over from del.icio.us to Ma.gnolia. Every single one of my bookmarks imported hit my feed in an aggregator. Every last one. Can you IMAGINE the mess of that hitting someone’s Facebook? Again using Dandelife as an example, I get a list via email at the end of the day broken down by person. I can quickly scan it to see what’s relevant, and if a mass changeover takes place like the one I described, it’s obvious, and I can skip right over it.

You could theoretically use FriendFeed as your central place for sharing links and then automatically import those items into Facebook using the “import feed” option for notes, since they also allow comments, without installing the FriendFeed application. And that would also mean that your non-Facebook loving friends would still be able to subscribe to your shared items if they wanted to (since Facebook doesn’t have a feed for notes or posted items).

If I find a link that I think is something I really want to share with everyone, I use the posted items feature on Facebook itself, which also allows an exchange of ideas via the comments.
